What are the best practices for type checking in Python?
The best practices for type checking in Python include using type hints, leveraging static type checkers like mypy, and keeping your codebase consistent.
Can you explain how to use type hints effectively?
Certainly! Type hints can be added using the typing
module. For example, you can specify a function's argument types and return type like this: def add(a: int, b: int) -> int:
.
What tools can I use for static type checking?
Popular tools for static type checking in Python include mypy, Pyright, and Pyre. They analyze your code for type errors before runtime.
